Answer:
Answer = $349 before buying the bike
Step-by-step explanation:
X x 2 - 50 = 299
50+299= 349
X x 2 = 349 x 2
2x =349 x 2
2x = 698
698 divided by 2 = <em><u>349</u></em>
Answer: x = 4
Step-by-step explanation:
3(x+2)=2(x+5)
3x + 6 = 2x + 10
x + 6 = 10
x = 4
200 + 10x = 375
x = 17.5, but round up to 18 because you can’t wash half of a car
